Sinterit introduces first PA11 for desktop SLS 3D printing

1Shares

Following the release of the Lisa Pro SLS system, Polish 3D printer manufacturer Sinterit has introduced a new powdered material to market. A nylon-based high performance polymer, PA11 Onyx is reportedly the first of its kind for use on desktop SLS 3D printers. The material has high chemical, abrasive and impact resistance, making it a hardy and robust choice for a variety of industrial and electrical applications.

“Traditionally PA11 has not really been widely used due to its challenges with repeat accuracy on old generation Laser Sintering machines,” explains designer Janne Kyttanen, who worked with Sinterit on some trial part examples. “[The] reason for that is controlling heat on large powder beds, which all of the previous machines have had,”

“When you bring this material to desktop size, you are changing the game. Small size platforms open up new opportunities not just in PA11, but also beyond.”

3D printing for unforgiving conditions

Sinterit PA11 Onyx is a lightweight bioplastic made from plant-based resources. PA11 provides higher heat and chemical resistance than its relative of Nylon 12. Additionally, in Sinterit’s case, PA11 has the flexibility of 3D printing on the desktop. The material’s excellent impact resistance is determined by a high elongation at break, making it ideal for functional applications and testing.

A glasses case, made to contain combat glasses, has been tried as an example application of PA11 Onyx. Hard wearing and robust, the case is made for use in typically unforgiving environments, withstanding harsh weather conditions and prolonged use. According to Sinterit, the PA11 case can be “opened and closed thousands of times” without wear.

Custom castings, such as Rasberry Pi housing, are also well-suited to PA11 Onyx. Konrad Glowacki, co-founder of Sinterit, explains, “Our clients use a lot of electronic devices, like Raspberry Pi, that need a proper, individually made housing that can endure in unfriendly conditions,”

“They are looking for durable materials but also require some elasticity and high-temperature resistance. PA11 Onyx delivers that.”
